On a recommended specification machine resolutions of 1152*864 should provide good performance. On a high end machine 1280*1024 on a standard 17 inch LCD monitor will give very good performance.2.2 CPU Speed-------------NBA 2K11 is optimized for dual core machines. If the game is run on a single core machine, a processor of 2.4GHz or better is required to get reasonable performance. The higher the clock speed of the processor the better the game will run. Most dual core machines will be optimum for NBA 2K11.NOTE: Performance is likely to be significantly slower with certain laptop video cards/processor configurations. Please ensure that your system configuration is in-line with at least the minimum system requirements.2.3 Memory----------Memory or RAM can sometimes greatly affect game play. Machines with less memory will access their hard disk more frequently to load data, which causes sporadic pauses in game play. Machines with a lower end processor and video card that has 256 MB of RAM or less, should make sure that there are no active running programs in the background. This will optimize performance and make the gaming experience better for the user.For good performance we recommend at least 1 GB of system memory. For optimum performance we recommend at least 2 GB of system memory.2.4 Better Performance for your Game------------------------------------If performance issues are observed, it is then recommended that the user selects a lower screen resolution as well as lowered detail settings from the video options screens (Options -> Settings -> Video Settings/Advanced Video Settings).=====================================================================3) Troubleshooting=====================================================================3.1 Installer Issues--------------------The NBA 2K11 installer will automatically patch to the latest version of the NBA 2K11 game application as part of the install process. Important Note: Game requires Internet connection for activation.If you are having trouble installing the game, please ensure that all active programs, particularly internet security programs, are closed prior to installation.3.2 Video Card Issues---------------------You can determine what video card is installed in your computer by right-mouse clicking on "My Computer" and choosing the "Properties" option. Once the "System Properties" menu appears, left-mouse click on the "Hardware" tab and choose the "Device Manager" option. Select "Display Adapter" to view your machine's video card. Search the web for your card to download updated drivers.After installing updated drivers you should also reinstall the current version of DirectX. You can download the most current version at: www.microsoft.com/windows/directx/default.aspxReboot the computer after installing new drivers or DirectX. This will ensure that any modified Windows files are fully updated or installed properly, prior to playing NBA 2K11.NOTE: Section above is written for Windows XP users. Other Windows Operating Systems may perform differently.3.2.1 Shader Model 3.0 Support------------------------------NBA 2K11 requires a video card with Shader Model 3.0 support in order to run.3.3 Sound Card Issues---------------------You can find out your machine's sound card by right mouse clicking on "My Computer" and choosing the "Properties" option. Once the "System Properties" menu appears, left mouse click on the "Hardware" tab and choose the "Device Manager" option. Select "Sound, video and game controllers" to view your machine's sound card. Search the web for your card to download updated drivers.After installing updated drivers you should also reinstall the current version of DirectX. You can download the most current version at: www.microsoft.com/windows/directx/default.aspxReboot the computer after installing new drivers or DirectX. This will ensure that any modified Windows files are fully updated or installed properly, prior to playing NBA 2K11.NOTE: Section above is written for Windows XP users. Other Windows Operating Systems may perform differently.3.4 Control Issues------------------Some PC keyboards can't recognize 3 or more simultaneous key presses; the keyboard buffer for the system overloads and, in some cases, will return a system beep.3.5 AMD Dual Core Timing Issue------------------------------Some older machines that have AMD dual core processors may experience problems running the game. If you have such a system, you should first visit the AMD website and obtain the latest processor drivers. You should only install this driver if you are confident that it is appropriate for your system (i.e. you have an AMD dual core processor).3.6 Virtual Memory------------------------------NBA 2K11 requires virtual memory to run properly. If your virtual memory settings are not correct, you may experience stability problems.To configure virtual memory:On Windows XP- From the start menu, open Settings/Control Panel.- Double click the System icon.- Select the Advanced tab.- Click on the Performance/Settings button.- Select the Advanced tab.- Click on the Virtual memory/Change button.- Select the drive that NBA 2K11 is installed on.- Select the "System managed size" radio button in the "Paging file size for selected drive".- Click the Set button.- Click OK multiple times to return to the desktop.On Windows Vista- From the start menu, open Settings/Control Panel.- Select System and Maintenance.- Select System.- Select Advanced System Settings.- Click on the Performance/Settings button.- Select the Advanced tab- Click on the Virtual memory/Change button.- Check "Automatically manage paging file size for all drives"- Click OK multiple times to return to the desktop.3.7 Installation failure------------------------If the installation fails for some reason then it is possible for the installer to be left in a state where installation can no longer be completed. In this situation it may be necessary to close down windows and restart the computer.====================================================================4) Updates to the Manual=====================================================================For further information on NBA 2K11 please check the 2K Sports website:www.2ksports.com=====================================================================5) Technical Support=====================================================================If you have a technical question about NBA 2K11, first check the in-game manual.If you are unable to find the answer to your question in the manual, please check the online Frequently Asked Questions (FAQ) in the forums at www.2ksports.comIf you've tried the above methods and are still unable to resolve your problem, please email Tech Support at techsupport@2ksports.comFor all other questions or inquiries, contact the Customer Service Department atcustomerservice@2ksports.com=====================================================================6) Copyright Notice=====================================================================(C)2010 Take-Two Interactive Software and its subsidiaries.
